Description

Technical Field

[0003]

[0001] This application relates to the technical field of pier brackets, and particularly to the formwork for pier brackets in lake areas. Background Art

[0002] In related technologies, a pier bracket is a cantilevered concrete structure protruding from the pier of a flood-diversion sluice. It is usually located at the top or side of the pier and resembles a "bracket" (a short and thick support arm). It is the connecting and transitional part between the pier and upper structures such as bridges and hoist platforms, and transfers the upper load to the main body of the pier through its own cantilever ability. The forming quality of the pier bracket concrete directly affects the structural safety and durability, and the traditional bracket formwork technology has the following problems:

[0003] Poor adaptability to special-shaped structures: Most brackets are broken-line cantilever structures. Conventional wooden formworks have many joints and low precision, which easily lead to surface offsets and leakage of concrete.

[0004] Leakage and durability defects: The high-humidity environment in lake areas accelerates the leakage of mortar at the formwork joints, forming honeycombed and pitted surfaces; wooden formworks are prone to water absorption and deformation, both of which affect the appearance quality and durability of concrete.

[0005] Low construction efficiency: The space of the bracket is narrow and the steel bars are dense. The installation of traditional formworks takes a long time and depends on manual experience, making it difficult to meet the urgent construction period requirements during the flood season in lake areas. Content of the Utility Model[[ID=2,0]]

[0006] To solve or partially solve the problems existing in related technologies, this application provides a formwork for pier brackets in lake areas, aiming to solve the problems of poor formwork stability, low construction quality and low construction efficiency in the concrete pouring of pier brackets.

[0007] This application provides a formwork for pier brackets in lake areas, including:

[0008] Left special-shaped formwork, right special-shaped formwork, end formwork, outer formwork, end part formwork and reserved holes for inspection bridges;

[0009] Left special-shaped formwork and right special-shaped formwork are installed on both sides of the reserved holes for inspection bridges. The upper ends of the left special-shaped formwork and the right special-shaped formwork are connected to each other, and the lower ends of the left special-shaped formwork and the right special-shaped formwork are respectively provided with beveled right-angle openings.

[0010] The end formwork is vertically installed on the right-angle opening of the left special-shaped formwork to close the end of the bracket.

[0011] The outer formwork is in the shape of "factory". One end of the outer formwork is installed on the right-angle opening of the right special-shaped formwork, and the other end is installed on the end formwork.

[0012] The end part formwork is a right-angled trapezoid. The end part formwork is installed at the upper and lower ends of the end formwork and the outer formwork to respectively close the upper and lower surfaces of the bracket.

[0013] Optionally, in some embodiments, the end template, the head template, and the outer template are tilted to the lower left as a whole to facilitate the later installation of the gate arm hinge seat.

[0014] Optionally, in some embodiments, the left irregular template, the right irregular template, the end template, the outer template, and the end template are made of 6mm thick steel plate.

[0015] Optionally, in some embodiments, the left and right irregular templates are arranged with No. 10 channel steels along the longitudinal spacing of the templates and are fully welded to the panel.

[0033] The quality of the concrete forming of the gate pier corbel directly affects the structural safety and durability. However, traditional corbel formwork technology has the following problems: poor adaptability to irregular structures: corbels are mostly zigzag cantilever structures, and conventional wooden formwork has many joints and low precision, which can easily lead to misalignment and grout leakage on the concrete surface; leakage and durability defects: the high humidity environment in the lake area accelerates grout leakage at the formwork joints, forming honeycomb pits; wooden formwork is prone to water absorption and deformation, both of which affect the appearance quality and durability of the concrete; low construction efficiency: the corbel space is narrow and the reinforcement is dense, and traditional formwork installation is time-consuming and relies on manual experience, making it difficult to meet the tight construction schedule requirements during the flood season in the lake area.

[0034] To address the aforementioned issues, this application provides a formwork template for the corbel of a sluice gate pier in a lake area. Through modular combination of irregular and standard templates, it achieves precise matching of the irregular shape of the corbel, effectively improving installation efficiency, enabling simultaneous construction of the corbel and the sluice gate pier, ensuring the quality of the concrete appearance and the overall structural form; optimizing construction procedures, accelerating construction progress, shortening the construction period, and reducing costs.

[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0041] The end formwork 3 is vertically installed on the right-angle opening of the left special-shaped formwork 1 and is fixed to the side formwork of the pier by tie rods for closing the end of the corbel. The outer formwork 4 is in the shape of "factory", processed into the designed curved surface by a hydraulic bending machine. One end of the outer formwork 4 is installed on the right-angle opening of the right special-shaped formwork 2 by bolts, and the other end is installed on the end formwork 3 by bolts.

[0042] The end formwork 5 is a right-angled trapezoid.
